如何从另一个.js文件添加快速路由端点?

server.js

const express = require('express');
const app = express();
const http_port = 8000;

app.listen(http_port,()=>{
 console.log(`app listening on port ${http_port}`);
});

app.get('/create_something',function(req,res){
 createSomething();
 res.send('create');
});

app.post('/update_something',function(req,res){
 updateSomething();
 res.send('update');
});

//and so on for 30 more endpoints

video.js 和 audio.js .

思考 this solution other_route.js :

var express=require('express');
var router=express.Router();

router.get('/other_route_endpoint',function(req,res){
    res.send('other_route_endpoint');
});

module.exports.router=router;

然后把这个包括在 server.js

const express = require('express');
const app = express();
const http_port = 8000;
var router=express.Router();
router.use('/other_route',require('./other_route').router);

但当我拜访 myserver.com:8000/other_route_endpoint

Cannot GET /other_route_endpoint

如何将其他文件中的端点添加到 ,所以我可以将它的一些端点移动到这些子文件中?
